The luminescent system exhibited unusual features which originated from the crystal chemistry aspects of the stillwellite system. The lack of orientation in the excited d-orbital of Ce 3+ enhanced the propensity to strongly interact with the p-orbital of the oxygen ions. The Ce 3+ in the matrices could serve as an efficient sensitizer for Tb 3+ as a codopant leading to intense green emission.journal article10.1088/0022-3727/34/17/3052-s2.0-0035822980https://www.scopus.com/inward/record.uri?eid=2-s2.0-0035822980&doi=10.1088%2f0022-3727%2f34%2f17%2f305&partnerID=40&md5=fa52a5f40e4b209b35860c26a4b16484
